Most investors think buying stocks with low P/E ratios guarantees safety and upside. In reality, relying solely on P/E has cost investors billions in missed opportunities. Here's what the smart money knows that most don't.
The P/E Trap
Consider INTC versus NVDA. Based on recent filings, INTC trades around 10x earnings while NVDA trades near 60x. Yet over the past decade, NVDA has compounded capital at roughly 25% annually while INTC has barely grown. This is the P/E trap: cheap stocks can stay cheap indefinitely if growth stalls.
What Makes a Good P/E?
The table below shows why context matters. High-growth companies like AMD and NVDA consistently outperform despite their lofty multiples. Meanwhile, low-P/E stalwarts like INTC and F have destroyed capital.

The Counter-Argument
Critics rightly point out that P/E works better in stable industries like consumer staples. Consider KO: at ~25x earnings, its consistent ~5% growth and 3% dividend yield have delivered solid returns. The key is matching valuation frameworks to business models.
Case Study: AMZN in 2015
In 2015, AMZN traded at ~500x earnings. Most value investors dismissed it as absurdly overvalued. Yet those who looked at cash flow conversion and reinvestment rates saw a compounding machine. Over the next 5 years, AMZN returned ~400%.
The Smart Money Framework
Warren Buffett's Berkshire Hathaway ($BRK.B) uses a three-part framework:
- Free cash flow yield > Treasury yield
- ROIC > 15%
- Stable or growing revenues
This approach avoids the P/E trap by focusing on cash generation. See more: Our guide to intrinsic value.
